  • the object is therefore to provide a device and a method for the continuous determination of the fat content of meat which do not have the disadvantages of the prior art. Furthermore, there is the task of providing a means for determining the flow rate and a method for adjusting the fat content in a meat mixture.
  • the object is achieved according to the invention by a meat processing machine with which fresh and / or frozen meat is chopped, filled, degassed and / or mixed and which has a fat analysis device for determining the fat content in the meat.

  • the meat processing device according to the invention is simple and inexpensive to produce. Existing meat processing devices can be retrofitted with the three measuring devices. The instantaneous meat mass flow through the meat processing device and its instantaneous fat content are determined at least semi-continuously, so that the average fat content of a resulting meat mixture can be determined and adjusted with these data.
  • a meat processing machine in the sense of the invention is any meat processing machine known to the person skilled in the art, with which meat is chopped, mixed, degassed and / or filled.
  • the meat processing machine is preferably a mixer, a filling machine or a comminution machine, in particular a grinder.
  • the fat analysis means preferably has a radiation source with preferably several energy levels and a radiation detector.
  • the radiation source is an X-ray source and the radiation detector is an X-ray detector.
  • An infrared source is also preferred as the radiation source and an infrared detector as the radiation detector.

  • the attenuation of the X-ray beam is preferably measured in an energy range between 18 and 40 keV.
  • the radiated meat layer thickness is preferably 50 to 80 mm, particularly preferably 65 to 75 mm.
  • the fat content and the control of the x-ray source are preferably calculated by a microprocessor or programmable logic controller (PLC control).
  • the fat analysis can be carried out at any point on the meat processing machine in which the measuring section is at least temporarily not interrupted by moving parts, in particular metal parts.
  • the meat processing devices often have conveying units, for example screw conveyors, and a comminuting unit, the conveying unit pressing the meat through the comminuting unit.
  • the fat analysis is then preferably carried out in the area of the conveying unit, it being particularly important in this constellation that the measuring section is at least temporarily not interrupted by moving parts, in particular metal parts.
  • the fat analysis can also preferably be carried out in a region between the conveying unit and the comminuting unit.

  • the temperature measurement is preferably integrated in the fat analysis device.
  • the temperature measurement can be used, among other things, to determine the physical state of the meat to be processed.
  • the meat processing machine according to the invention additionally has a speed measurement so that, in addition to the instantaneous fat content and the instantaneous temperature, the instantaneous speed of the meat can also be determined, the fat content and the flow rate not having to be measured at the same point.
  • the instantaneous flow velocity of the meat is advantageously measured using an optical measuring method and preferably after it has been processed, for example comminution.
  • the optical measuring method is preferably based on a light source, preferably a halogen lamp combined with a CCD camera.
  • the speed measurement is very particularly preferably carried out in a discharge chute which is preferably arranged after the meat has been processed, for example its comminution by means of a perforated disc.
  • This channel is at least partially open upwards, so that the speed measurement takes place at least almost at ambient pressure.
  • the trough has at least one window on which a means for preferably optically determining the flow rate of the meat in the discharge trough is arranged.
  • This discharge channel is therefore also the subject of the present invention.
  • the discharge channel has the advantage that the meat does not smear during the speed measurement and that there is permanently a defined distance between the meat flowing past and the speed measurement.
  • the discharge channel can be connected directly to the meat processing device or integrated into it.
  • the discharge channel is simple and inexpensive to manufacture and easy to clean.
  • all measurements are carried out continuously and the evaluation is carried out every 1-2 seconds.
  • Another object of the present invention is a method for determining the average fat content of the meat of a mixture, which in a Meat processing machine is processed, in which the instantaneous fat content of the meat and its instantaneous mass flow are continuously measured and thus the average fat content in a resulting meat mixture is calculated.
  • the instantaneous mass flow is preferably calculated using the following formula:
  • the correlation factor b is a function of the temperature of the meat to be processed and also depends on the type of shredding in a shredding machine.
  • the temperature of the meat to be processed is therefore preferably measured. This measurement is preferably carried out in the vicinity of the location of the meat processing machine, at which the instant fat content of the meat is also determined.
  • the average fat content of a resulting mixture is preferably according to the formula:
  • This method has the advantage that there is no delay in the analysis of the average fat content of the meat of a mixture. No additional devices have to be provided to determine the average fat content of the meat.
  • the fat content can be determined in both fresh and frozen meat. The consistency of the meat is not changed by the method according to the invention.
  • the fat analysis is preferably carried out during comminution, mixing and / or filling, preferably with X-rays.
  • comminution mixing and / or filling, preferably with X-rays.
  • Another object of the present invention is a method for adjusting the fat content in a mixture, using a
  • Meat processing machine in which the meat processing machine can be loaded with at least two flow rates, which differ in their fat content, the actual fat content of the resulting mixture is continuously determined, a target fat content is specified and the mixing ratio of the flow rates is changed in the event of a target / actual deviation ,
  • the process according to the invention has the advantage that the average fat content of a mixture can be specifically adjusted or continuously changed without the production process having to be changed.
